Carrillo SC7608-4 Pro-H Connecting Rod Set with CARR Bolts

These rods are equipped with Carrillo's CARR (S-series) rod bolts, the upgraded fastener option designed for high-RPM and high-horsepower applications.

Key Features:

• Forged from Carrillo's proprietary Carrilloy (4330M chromoly steel) — a chrome, nickel, moly, vanadium alloy meeting VAR (vacuum arc re-melt) ASTM standards
• Fully machined from oversized forgings to ensure proper grain flow and removal of surface inclusions
• Each rod is 100% magnaflux inspected twice and Rockwell hardness tested after heat treatment
• Final controlled shot peen operation relieves tensile stress and maximizes fatigue life
• CARR S-series rod bolts feature asymmetrical threads for evenly distributed thread engagement, increased clamp load, and superior fatigue life
• Each set includes a spec card with part number, critical dimensions, weights, job number, and bolt installation chart
• Manufactured in the USA

CP-Carrillo connecting rods are trusted by top engine builders across drag racing, road racing, oval track, and high-performance street applications. The CARR bolt configuration is the preferred choice for extreme output builds and engines operating at elevated RPM levels, offering an ultimate tensile strength (UTS) of 285,000 psi via the MP35N alloy fastener.
